PRN 13650 Building recording was undertaken in 2002. The Johnson family seed business was founded in 1820 and grew in dominance at the turn of the nineteeth/twentieth century to become the largest independent seed producer in the country. The two warehouses in the Stells Lane complex were opened in 1906. However, by the 1970s much seed produce was being imported from abroad or other parts of Britain, placing less emphasis on the need for the Boston warehouses.{1} Warehouse 1 is essentially of single-phase construction, surviving largely unaltered. A small building had been added against the east side at a later date and subsequently removed. Warehouse 2 is also essentially of single-phase construction, although several additional structures were subsequently built against the south side and more alteration to the building has taken place.{1} Warehouse 1 is a four-storey brick-built structure in a concrete frame with a corrugated pitched roof. It is elongated north/south, eleven window bays long and four window bays wide. The windows are wooden or steel frames with concrete sills, generally three panes by three panes, though some smaller windows were noted in areas of limited access. The northern elevation is divided into four bays, while the southern elevation is divided into three larger bays, with each bay having a nine-panel window. Internally, the warehouse has four floors. The ground floor is based in concrete while the other storeys have timber floors. The central aisle of each floor has twenty parallel upright I-section roofing support joists supporting the ceiling and the floor above. A centrally-located sack hoist extends through all floors, with two further sack hoists at the south end of the building from the first floor upwards.{1}{2} Warehouse 2 is a five-storey brick-built structure in a concrete frame, with a basement (access to the basement was limited due to flooding). The warehouse is elongated east/west and divided into thirteen bays; the east and west elevations are divided into three bays. The roof is flat with an upstanding architrave along the top of the north elevation and metal railings along the tops of the other elevations. Located centrally on the roof is a wooden shed housing the sack hoist mechanism, which displays a metal plate with 'PICKERING LTD GLOBE ELEVATOR WORKS STOCKTON-ON-TEES' on it. The north elevation has a road approach, reflected in the more impressive façade with architrave and an imposing central bay. The windows are generally sixteen or eighteen panes with a mixture of wooden and UPVC frames. The central bay is more ornate with twenty-four pane windows. The fourth bay has a sequence of wooden doors with glass panelling in the top half. The southern elevation is mainly a mirror-image of the northern, though less impressive and lacking the large windows of the central bay. A three-storey brick structure has been added to the western end of the building, and a single-storey structure has been added at the eastern end, possibly as a boiler room. The second floor has had considerable external alteration, with brick blocking added to several bays. The western gable has a painted sign, 'Johnsons Seeds', located centrally at the top of the building. This would have been a form advertising from the former rail-yard and line which ran to the east of the warehouse. Internally, the building is divided into two wings, with all the floors being timber. The ground and first floors have internal plasterboard divides creating individual office spaces, while the second to fourth floors are open-plan. Timber and concrete stanchions through the central aisle support floors and ceiling.{1}{2} The buildings have been demolished. {3}
